JSS FOCUS ISSUE ON PRINTABLE FUNCTIONAL MATERIALS FOR ELECTRONICS AND ENERGY APPLICATIONS Ultrafast Atmospheric-Pressure-Plasma-Jet Sintering of Nanoporous TiO2-SnO2 Composites with Features Defined by Screen-Printing

compositeswithpatternsdefinedby the screen-printing technique. The pastes used for screen-printing were made of oxide nanoparticles and organic binders. Afterusing screen-printing to define the features, APPJ was then used to rapidly sinter the screen-printed pastes. APPJ sintering for 30 scan efficiently remove the organic compounds and sinter the nanoparticles, with transmittance haze values comparable to thoseof nanoporous oxides prepared by conventional furnace calcination. Dye-sensitized solar cells with APPJ-sintered photoanodes(sintering time ≥1 min) showed efficiencies comparable to or exceeding those of cells prepared by conventional furnace calcination.© The Author(s) 2015.
